Penrith Castle was begun at the end of the 14th century by Ralph Neville, who played a key role in defending this area against the Scots. It was later transformed into a luxurious residence by Richard, Duke of Gloucester, who became Richard III. Surviving to their full height, the castle walls stand in a public park.
